Taiyuan University of Technology Reports Findings in Astrophysics Research (Structural, electronic, and optical absorption properties of TiO2 nanotube adsorbed with Cu-n clusters)

By a News Reporter-Staff News Editor at Physics Week -- Research findings on Astrophysics Research are discussed in a new report. According to news reporting originating from Taiyuan, People's Republic of China, by VerticalNews correspondents, research stated, "The structural, electronic, and optical absorption properties of TiO2 nanotube (TiO2NT) with Cu-n clusters (n = 1-4) adsorbed on its surface have been investigated based on density functional theory calculations."

Our news editors obtained a quote from the research from the Taiyuan University of Technology, "The TiO2NT is constructed by rolling up a (101) sheet of anatase TiO2 around the [(1) over bar 01] direction; the ground states of Cu-n/TiO2NT systems are determined by analyzing the average adsorption energies. Calculation results show that odd-even oscillations occur for the average adsorption energy, the Cu-O bond length, and the amount of transferred electrons, with the increase in Cu cluster size; and the Cu-n/TiO2NTs with odd n's demonstrate stronger interaction between the Cu cluster and the TiO2NT."

According to the news editors, the research concluded: "Also, the impurity states introduced by the Cu-n cluster to the band gap of TiO2NT cause an obvious redshift of the optical absorption spectrum toward the visible light region, especially for the even n cases."
